  2. What do commercial solar cookers look like? All angled sides lined with aluminum foil Clear plastic over container Black container that holds food

  3. Let’s put them to the test!

  4. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm

  5. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm What is the problem the family is investigating?

  6. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm What is the problem the family is investigating? What time of day is solar energy the strongest ?

  7. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm What is the independent variable in this investigation?

  8. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm What is the independent variable in this investigation? Time of day

  9. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm How can we make this a more controlled experiment?

  10. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm How can we make this a more controlled experiment? The amount of water in each beaker should be the same.

  11. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm What must we do before we begin the experiment?

  12. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm What must we do before we begin the experiment? Measure the temperature of the water in the beaker.

  13. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm What is the dependent variable in this experiment?

  14. Testing the cookers 45 mL water 50 mL water 45 mL water 12 pm – 2 pm 2 pm – 4 pm 10 am – 12 pm What is the dependent variable in this experiment? The change in temperature of the water.

  15. What is the purpose of the aluminum foil? All angled sides lined with aluminum foil Clear plastic over container Black container that holds food

  16. What is the purpose of the aluminum foil?To reflect the light onto the cooking area. All angled sides lined with aluminum foil Clear plastic over container Black container that holds food

  17. What is the purpose of the clear plastic cover over the container? All angled sides lined with aluminum foil Clear plastic over container Black container that holds food

  18. What is the purpose of the clear plastic cover over the container?To block the warmed air in the container from escaping. All angled sides lined with aluminum foil Clear plastic over container Black container that holds food
